Except we have to use gameplay, because that's what the classes are balanced around. If we went on just lore, you could add any class you want to the game and have no overlap problems whatsoever. Warlocks for example could still have metamorphosis, because lore-wise nothing happened to make them lose the spell. Demon Hunters could have Mana-burn because it is one of their original spells from WC3.
Except gameplay-wise Warlocks lost metamorphosis because Blizzard didn't want two classes having the ability to transform into demons. Demon Hunters aren't getting Mana-Burn because being able to harm the resources of other players is OP, and stealing mana from monsters is mostly useless gameplay wise.
Lore-wise Necromancers should have no problem being a class in WoW. Gameplay-wise Death Knights and Warlocks suck up nearly all of their design space, and Blizzard used the Necromancer concept to create Death Knight gameplay.

Holy Priest have Mind Control, which is a shadow ability.
Discipline actually has quite a few Shadow abilities. In fact, a good portion of their talent tree utilizes Shadow abilities.
That's all lore. We're not talking about lore, we're talking about abilities and gameplay, and the theme that arises from those abilities and gameplay.Shadow priest are Shadow priests (a scattered few, mostly forsaken but also some Dark Irons and Humans who focus entirely on shadow magic). The vast majority of priests in the lore, as notable figures, and among players, are not Shadow priests. Velen is not a shadow priest, he does not use shadow magic.. What is the difference between Prophet Velen and Yrel? Yrel chose to pick up a hammer and fight that way. What is the difference between High Inquisitor Whitemane and Alexandros Mograine? Mograine wears plate and uses the Ashbringer and Whitemane wears robes and uses raw destructive light magic.
Whitemane is not a shadow priest. She does not use any shadow magic, and her entire character is built around the destruction of undead.
I'm going to guess you haven't done the Paladin campaign, because there is literally a priest who helps you out and then decides she'd be able to do more by joining the Silver Hand and becomes a Paladin simply by reciting the oath and switching over from her robes and bow to a set of plate armor and a warhammer.
No, but that wasn't the argument. The argument was are they using a musical instrument to cause a magical effect. If you're utilizing your voice, you are using an instrument. Its no different than a kid banging on the drums or slamming cymbals together, they're not making music, but they're still using an instrument.When it is used to sing or make music. Is Dragon Roar music? No.
No, because the wine-glass isn't producing sound when you're drinking from it. A Roar is definitely a sound coming from your vocal chords.A wine glass is a musical instrument when it is used as one. That doesn't mean drinking a potion out of a wine glass to heal yourself, and playing a lyre to heal yourself are the same thing.
